Summary

Javascript Foreach Example is today’s leading topic. forEach() is the Array method that we can use to execute a function on each item in an array. It can only be used on the Javascript datatypes like Arrays, Maps, and Sets. It is the A function to be run for each item in the array. The forEach() executes the provided callback once for each element present in the array in ascending order.

The prototype constructor allows us to add new properties and methods to the Array() object itself. There are already some methods available in the Javascript, and one of them is forEach. When constructing the property, All arrays will be given the property, and its value, as default. When constructing a method, All arrays will have this method available. A prototype is a global object constructor which is available to all the Javascript objects. Let us take an example of that.
